mxt-touch: Pull support for atmel mxt touch from dunfell branch

* imx6:mxt-touch: Add kernel support for atmel mxt touch
  BCS 746-000886
  (cherry picked from commit 82cbcf67)

* maxTouch:udev: Add udev rule to skip maxTouch fwr loading fallback

  The current version of the atmel_mxt_ts driver tries to load a controller
  configuration on each driver probe. However, if no config is provided or
  can't be provided because the driver is built-in, the driver probing process
  is delayed by 60 seconds because of a sysfs firmware load fallback.
  Added a udev rule that automatically cancels the sysfs firmware fallback.
